Artificial intelligence
Artificial intelligence (AI) is the ability of a digital computer or computer-controlled robot to perform tasks commonly associated with intelligent beings. The term is frequently applied to the project of developing systems endowed with the intellectual processes characteristic of humans, such as the ability to reason, discover meaning, generalize, or learn from past experience. Since their development in the 1940s, digital computers have been programmed to carry out very complex tasks – such as discovering proofs for mathematical theorems or playing chess – with great proficiency. Despite continuing advances in computer processing speed and memory capacity, there are as yet no programs that can match full human flexibility over wider domains or in tasks requiring much everyday knowledge. On the other hand, some programs have attained the performance levels of human experts and professionals in executing certain specific tasks, so that artificial intelligence in this limited sense is found in applications as diverse as medical diagnosis, computer search engines, voice or handwriting recognition, and chatbots.
All but the simplest human behavior is ascribed to intelligence, while even the most complicated insect behavior is usually not taken as an indication of intelligence. What is the difference? Consider the behavior of the digger wasp, Sphex ichneumoneus. When the female wasp returns to her burrow with food, she first deposits it on the threshold, checks for intruders inside her burrow, and only then, if the coast is clear, carries her food inside. The real nature of the wasp’s instinctual behavior is revealed if the food is moved a few inches away from the entrance to her burrow while she is inside: on emerging, she will repeat the whole procedure as often as the food is displaced. Intelligence conspicuously absent in the case of the wasp must include the ability to adapt to new circumstances.
Psychologists generally characterize human intelligence not by just one trait but by the combination of many diverse abilities. Research in AI has focused chiefly on the following components of intelligence: learning, reasoning, problem solving, perception, and using language.

One pathway for converting explicit to implicit knowledge is suggested by skill acquisition theory, a branch of cognitive science studying how people develop skills. In this theory, knowledge is first seen to be declarative (conscious); then, through practice and the application of learning strategies, declarative knowledge becomes proceduralized so that it becomes automatic. Automatic processes are quick and do not require attention or conscious awareness. Many second/ foreign language learners memorize and practice vocabulary items or “chunks” of language such as greetings, idioms or collocations. Frequent practice in using these forms helps the language items to become automatic in the sense that the learner can use them quickly and unconsciously.
Pienemann (1989) proposes that second/ foreign language learners will not acquire a new structure until they are developmentallly ready to do so. If there were no connection between the development of explicit knowledge about a grammar point and the eventual restructuring of the unconscious linguistic system to accommodate the point in the learner’s interlanguage, then, indeed, grammar instruction would not be of much use. However, it has been suggested that there is a connection, so grammar instruction is ultimately useful. Further, practice of language points can lead to automatization, thus bypassing natural order teachability considerations.

The disjunction between method as conceptualized by theorists and method as conducted by teachers is the direct consequence of the inherent limitations of the concept of method itself. First and foremost, methods are based on idealized concepts geared toward idealized contexts. Since language learning and teaching needs, wants, and situations are unpredictably numerous, no idealized method can visualize all the variables in advance in order to provide situation-specific suggestions that practicing teachers need to tackle the challenges they are confronted with every day of their professional lives.
Not anchored in any specific learning and teaching context, and caught up in the whirlwind of fashion, methods tend to wildly drift from one theoretical extreme to the other. At one time, grammatical drills were considered the right way to teach; at another, they were given up in favor of communicative tasks. At one time, explicit error correction was not only favored but considered necessary; at another, it was frowned upon. These extreme swings create conditions where certain aspects of learning and teaching get overly emphasized while certain others are utterly ignored, depending on which way the pendulum swings.
The limitations of the concept of method gradually led to statements such as “the term method is a label without substance” (Clarke, 1983, p. 109), and that it has “diminished rather than enhanced our understanding of language teaching” (Pennycook, 1989, p. 597). This realization has resulted in a widespread dissatisfaction with the concept of method.
